Worried that a power outage might prevent you from playing video games? Worried you might have to do something unimaginable, like talk to other people?

Fret not! I've crunched some of the numbers, and as long as you're up to date on your portable gaming, you should be able to avoid human contact for almost two entire days. Forty-seven hours. If you take time to eat and sleep, that could be enough to get you through one serious power failure. (And I'm not even counting any gaming devices that have batteries! If you're stocked up, that Game Boy Color could last you the next four weeks.)
